Microsoft VBScript Scripting Engine Could Allow Remote Code Execution Vulnerability

Last Update Date: 28 Jan 2011 Release Date: 14 Apr 2010 5240 Views

RISK: Medium Risk

A remote code execution vulnerability exists in the way that VBScript interacts with Windows Help files when using Internet Explorer. If a malicious Web site displayed a specially crafted dialog box and a user pressed the F1 key, the Windows Help System would be started with a Windows Help File provided by the attacker. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. On systems running Windows Server 2003, Internet Explorer Enhanced Security Configuration is enabled by default, which helps to mitigate against this issue.
